Finally figured out how to lay out a cone pattern without guessing

Used to just eyeball my transitions and hope the scribe marks lined up... took me 3 tries last month on a duct job in Portland before I got the fit right. Finally broke down and used the parallel line method step by step - what's your go-to trick for cone layouts?

nah eyeballing is faster and works fine 90% of the time

and honestly that other 10% usually isn't bad enough to matter anyway.

Wait, do you actually get away with that most of the time? I used to be super against it because I thought you'd always end up with a crooked cut or waste material. But honestly, after watching a few videos where people just eyeball stuff and it turns out fine, I started trying it myself and yeah, it works way more often than I expected. Like, maybe it's just me but I think the whole "measure twice" thing is kinda overhyped for casual projects. I mean, for something like building a shelf in your living room, sure, be precise. But for quick weekend stuff, eyeballing is totally the move.
